A single-deck Blackjack game typically offers a lower house edge, around 0.17%, because there are fewer cards in play, making it easier for players to predict outcomes and more advantageous for card counting. The probability of drawing a Blackjack is higher in single-deck games, and decisions can be made with more accuracy. In contrast, a 6-deck shoe increases the house edge to about 0.60%, as more cards are in play, which reduces the predictability of outcomes and makes card counting less effective. The larger deck size also means a lower chance of hitting a Blackjack, and although deeper penetration (more cards dealt before reshuffling) allows for some tracking, the advantage is still weaker compared to single-deck games. Overall, while the single-deck game is more favorable for skilled players, a 6-deck shoe slows down the game and introduces more uncertainty, raising the house edge slightly.
